SPECIFICATION forming part of Letters Patent N 0. 651,512, dated June12, 1900. Application filed September 16, 1899. Serial No. 730,76 8. (N0model.)

To all whom it may concern:

Be it known that I, WARREN W. PHILBRICK, 0.1 Seattle, in the county ofKing and State of Washington, have invented a new and useful Improvementin Matcher-Heads, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, whichform a part of this specification.

Myinven tion relates to certain new and usef ul improvementsinmatcher-heads for use in tonguing, grooving, rabbeting, joining, andotherwise matching the edges of boards, and more particularly tomatcher-heads of the character described and claimed in my patentsofAugust 1,1899,Nos.629,8l3 and 629,814, and in my pending applicationsSerial Nos. 712,291 and 712,292, in which the work of matching the edgesof boards is divided between jointing blades or cutters having ashearing out toward the intermediate-portion of the edges of boards andcircular bits'or cutters which form the tongue, groove, or rabbet.

The object of the present invention is to provide novel means forseating the circular bits intermediate the jointing blades or cuttersand for adjusting the same to vary the degree of separation between theplanes of the cutting edges of the said bits; and the invcntion consistsin the novel construction and combination of parts, all as hereinafterdescribed, and pointed out in the appended claims, reference being hadto the accompanying drawings, in which Figure l is a side View of amatcher-head embodying my invention and adapted for the formation oftongues. Fig. 2 is a plan View of the same. Fig. 3 is a detailperspective View of one of the adjustable bit-seats detached, and Fig. 4is a detail view of one of the bits. Fig. 5 is a detail View of one ofthe cutters.

In the drawings the letter A designates the head proper, secured to arotary spindle in the usual manner'and provided at opposite sides withshouldered seats 0 for the jointing blades or cutters D, slotted at d,to pass the tongue. The inner walls of said seats are inclined upwardlyand inwardly toward the axis of the head, and the bottom walls arepitched downwardly the direction of rotation,

these provisions being for the purpose of giving the straight cuttingedges of the blades a shearing action downward from the upper edge ofthe board toward the tongue. For double-matched work,however,or workwhere the joint is to show from both sides it is preferred to use.jointing-blades of the character described and claimed in my saidpatents of August 1, 1899, which have a shearing action from bothsurfaces of the board toward the tongue or groove.

Plan ed or otherwise formed as the sides of the head between thejointing-blades and adjacent to the rear end of the seats for the latterare vertical grooves or guides E to receive the vertical arms F ofbit-carriers F These bit-carriers are shown as being somewhat in theshape of the letter L, the vertical arms fitting the said grooves orguides and the horizontal arms lying around against the sides of thehead. They are secured to the head by means of cap. or set screws G,which pass through vertical slots g in the arms F into the back walls ofthe grooves.

H designates the circular bits, which are similar to those employed inmy said patents, having receding beveled cutting edges h and shoulders hand seated in reversed positions on the under sides of the horizontalportions of the bit-carriers, being secured by bolts 1, the upper endsof said bolts having angular heads 2', which engage shoulders t" on thebit carriers, and thereby hold the bolts from turning in their seats.the bit-carriers may be somewhat inclined, as shown, in order to givethe bits clearance and cause them to cut somewhat deeper at the base ofthe tongue. In a grooving-head the bits will be flat cutting-disks ofthe character described in my said patents.

To vary the vertical distance between the cutting edges of the two bits,the screwsG are loosened and the bit-carriers are moved up or down inthe guides or grooves to the desired extent, which may be indicated by ascale marked on the head, after which the screws are again tightened. atongue of any desired thickness or a groove of any desired width may beformed.

For special work I may of course usejointing blades and bits havingcutting edges adapted to the particular work to be done.

The bit-seating faces of In this manner IOO The present improvement maybe applied to various matcher-heads now in use by planing the guides orgrooves in the head and providing the bit-carriers and bits.

In operation the jointing blades or cutters have a shearing action fromthe edge of the lumber toward the tongue, thereby preventing splitting,breaking, or chipping of the upper angles of the jointed edges, whilethe circular bits dress the faces of the tongue (or walls of thegrooves) and throw out the shavings formed by the jointing-bits,preventing the latter from burning, as they otherwise would.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a matchenhead, the combination with the jointing-blades arrangedto joint the vertical faces of the edges of the lumber, of independentbit-carriers secured to the head between the said jointing blades,circular bits or cutters seated thereon and operating to impart aspecial configuration to the edges of the lumber, and means foradjusting said bit-carriers to vary the degree of separation of thecutting-planes of the said bits or cuttors.

2. In a m atcher-head, the combination with the head proper havingjointing-blades ar ranged to make a shearing cut, of independentbit-carriers secured to opposite sides of the said head between the saidblades, means for adjusting said carriers vertically and cutting-bitsseated on the said carriers.

3. In a inatcher-head, the combination with the head proper havingjointing-blades arranged to make a shearing cut, of independentbit-carriers secured to opposite sides of the head intermediate the saidblades, means for vertical adjustment of the said carriers, andcutting-bits seated in reversed positions upon the said carriers.

4. In a niatcher-head, the combination with the head proper havingjointing-blades secured to the wings, and intermediate of said bladesupon its remaining sides vertical grooves or guides, of a bit-carrierseated in each groove or guide and vertically adjustable therein, and acutting-bit secured to each of said bit-carriers.

5. In a matcher-head the combination of the head proper havingjointing-blades secured to its Wings, and intermediate of said wings,upon its remaining sides, vertical grooves or guides, an L-shapedbit-carrier adjustably secured in each of said grooves or guides, boltspassing through the horizontal portions of the said carriers and havingangular heads engaging shoulders on said portions, and circularcutting-bits secured by the said bolts.

6. In a matcher-head, the combination of the jointing-blades secured toopposite sides of the said head and arranged to joint definite portionsof the edges of the lumber, of independent bit-seats fixed one to eachof the remaining sides of said head, and beveledge grooving-bits, one ofwhich is secured to each of said seats, the two bits being seatedreversely with respect to each other.

In testimony whereof I have affixed my signature in presence oftwowitnesses,

WARREN W. PI-IILBRICK.
